Yesterday Josh Thompson, one of my Rubber Duck Session clients, proposed a novel idea for deliberately practicing coding skills: take a popular open-source project with a good test suite, delete a class, and re-implement the class using only the tests as a guide. Then, compare and contrast our implementation with the original!

I suggested the Rake codebase, and this video is an unedited recording of the session. Enjoy!
